DOUBLE o'u LTIVATIOR.

SPECIFICATION forming part of Letters Patent No. 595,674, dated December14, 1897. Application filed August 16,1897. Serial No. 648,418. (Nomodel.)

1'0 aZZ whom it may concern:

Be it known that I, JAMEs K. DEATON, a citizen of the United States,residing at Concord, in the county of Oabarrus and State of NorthCarolina, have invented new and useful Improvements in DoubleCultivators, of which the following is a specification.

It is the object of my invention to provide a double cultivator having asimple and inexpensive construction and combination of parts whereby thetwo points from which the parallel lines of draft lead to the beams ofthe plows canbe so adjusted as to accommodate the nature of the crops tobe cultivated and at the same time control the depth of cultivation. Itis my purpose, in other words, to provide a double or multiple plowcultivator having a novel construction and arrangement of theconstituent parts by which crops of such a nature as to permit the useof plowcultivators may be cultivated to any depth of soil desired andwith such ease and rapidity as to enable the operation to be repeatedfrequently during-the period of growth, thereby increasing the rapidityof development, improving the quality, and largely increasing the yield,while at the same time the expense is largely diminished, since two rowsare cultivated simultaneously by two men and a single horse or mule. Theimportance of frequent and rapid cultivation of young crops is too wellknown to require any explanation.

My invention consists, to the ends specified, in the several novelfeatures of construction and in the new combinations and arrangements ofparts hereinafter fully described,and then particularly pointed out anddefined in the claims which conclude this specification.

To enable others to clearly understand and to make and use my saidinvention, I will now proceed to describe the same in detail, referencebeing had for this purpose to the accompanying drawings, in which--indicates the draft-axle, which is preferably cylindrical in form, beingconveniently constructed with the central portion of wroughtiron pipe,into the ends of which are fitted two solid extension-pieces 1, capableof longitudinal adjustment to adapt the plows to the width of the rows.These parts are locked in position when once adjusted by means ofset-screws 2, which are tapped through the central part 1 and bear attheir ends against the solid extension-pieces 1. The axle is supportedupon suitable wheels 3 and is provided with a pair of shafts 4 or anypreferred form of draft device.

Upon each of the solid extension-pieces 1 is mounted a end 5, capable ofa longitudinal movement upon the piece 1, and also having a swivelingadjustment thereon by which it may be turned or rotated in eitherdirection. Each cuif is provided wit-h a set-screw or setbolt 6, bywhich it is firmly looked after either or both adjustments are made.Each cuff is provided with a straight arm 7 of suitable length, whichprojects from the cuff at a right angle to the axis of the sleeve. Uponthe end of each arm is a hook 8 or an equivalent device for engaging theend of awire rope or chain 9. Upon the central tubular portion 1 arecentrally-arranged cuffs 10, from each of which projects a similar arm12, having at its end a duplex hook or fastening 14, which holds thesecond end of one of the chains or wire ropes 9. I may, however, use asingle hook or fastening for both.

The cultivating-plows may be of any preferred type-such, for example, asthe A- frame plows shown. Each plow is connected to one of the chains 9by means of a yoke 15, having a pulley 16, which is free to travel onthe chain. By adjusting the ends 5 inward or toward the central cuff 10the intervalof separation between the plows may be diminished to anyextent required. As the pulleys 16 travel freely on the ropes or chains9 the line of draft will always pass through the axis of each pulley andthe horizontal angle which is made by the line of draft on the plow willbe the same, normally, as the draftline upon the other side of saidaxle. By turning the ends upon the axle the arms projecting from themcan be made to stand at any desired angle. For example, they may hangstraight downward and the draft-line being brought so low theplow-shovels will be caused to seek a greater depth. By adjustmentsbetween said position and a horizontal plane the depth of cultivationmay be varied to any extent. Moreover, by turning the central cuff sothat its arm will point upward or at a suitable angle between ahorizontal and vertical line, and by giving the other cuffs suchadjustment that their arms will have a suitable downward inclination, aseparation between the two plows may be obtained which it is impossibleto obtain by the outward movement of the cuffs 5. The depth ofcultivation will be more or less varied by this adjustment, and it willbe observed, also, that by separately adjusting the cuifs the plows maybe caused to cultivate at different depths. Should the nature of theground or the arrangement of the crops make it advisableas, for example,where difierent crops are planted in alternate rows-this variation willbe found to promote the convenience and rapidity of cultivation to amarked degree.

By my invention two men and one horse can easily cultivate ten to twelveacres daily, and under favorable circumstances fifteen acres would notbe an excessive days work. The plows will seek a depth which will becontrolled by the position of the arms on the cuffs and will require nospecial attention from the operatives, who need only guide the plows.They will turn at the ends of the rows with great facility and can bedrawn behind the draft-axle in going toand from the field by merelyhitching the loops into the hooks or other fastenings 14. This willraise the nose of each plow so far that the shovels resting on theground will slide upon those portions behind the points of said shovels.

I may evidently use three cultivating-plows instead of two without anydeparture from my invention, and in some cases this change may bedesirable.

What I claim is- 1. A cultivator consisting of a wheeled axle providedwith cuffs having means for attaching the ends of chains or otherflexible connections to the ends of arms projecting from said cuffs, anda plurality of plows, each having a pulley connecting it to one of saidchains or connections, substantially as described.

2. In a cultivator, the combination with a wheeled axle consisting of acentral piece and two end extensions, of cuffs arranged on said partsand capable of longitudinal and rotary adjustment, each cuff having arigid arm projecting from it provided with a suitable attaching deviceat its end, suitable flexible connections such as chains attached tosaid devices, a plurality of cultivating-plows each having a pulleywhich rides upon one of said flexible connections, and means forfastening the cuffs when adjusted, substantially as described.

3. In a cultivator, the combination with an axle supported by wheels ofseparate cufis having longitudinal and rotary adjustment thereon, aplurality of cultivating-plows each having a pulley connected to itsforward end, slack flexible connections having connection to armsprojecting rigidly from said on ifs each connection having one of thepulleys riding thereon, and means for lockin g the cuifs upon the axle,substantially as described.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
